Sensor Calibration of ESP (R)

NOTE:

- If any DTC other than C1074, C1075 is detected, sensor calibration cannot be completed. Repair trouble cause of DTC first.
- ESP (R) hydraulic unit / control module assembly stores reference point of master cylinder pressure sensor and yaw rate / G sensor. Also steering angle sensor stores its own reference point.
Traction control and stability control are performed according to the variation of these sensors from their reference points. If a reference point is lost or shifted due to following maintenance, calibration is needed.






- All sensors are calibrated at once when calibration is performed.

1) Set steering wheel in straight-ahead position.
2) Connect SUZUKI scan tool to DLC (1) with ignition mode of keyless push start system in "OFF".
Special Tool

(A): SUZUKI scan tool (SUZUKI-SDT)





3) Push engine switch to change ignition mode of keyless push start system to "ON" and confirm that no DTC is detected except C1074, C1075. If any DTC is detected, repair or replace trouble area.
4) Park vehicle on level surface, apply parking brake, stop engine with ignition mode of keyless push start system in "ON", set steering wheel in straight-ahead position and release brake pedal.

NOTE:
Keep the above condition in Step 4) to calibrate sensor correctly until sensor calibration is completed.

5) Select menu "Sensor Calibration" under "Utility" mode of SUZUKI scan tool and calibrate sensor with ignition mode of keyless push start system in "ON". Refer to scan tool operator's manual for further details.
6) After completing the calibration, check DTC(s) is not stored in ESP (R) hydraulic unit / control module assembly.
7) Confirm that ignition mode of keyless push start system is in "OFF" and disconnect SUZUKI scan tool from DLC.
